Chaps, My 320ci is also having the same problems. It happened today after i inflated my tyres (32 at back and 29 in front) and i was driving behind a Hay Truck for a while which was spilling Hay everywhere and so i'm wondering if there may be Hay stuck in my Traction system? Is that possible or am i just making up problems here?
Anyhow, If i wanted to clean the sensors, where would i find them? Thanks
